How to grow Dutch Explosion Dahlia seeds

Choose Your Planting Method

• Indoors: Start 6-8 weeks before the last frost.
• Outdoors: Sow after the last frost once the soil reaches about 65°F (18°C).

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Good-quality seed-starting mix
• Humidity dome or plastic wrap

Sowing the Seeds

• Sow 1/2 inch deep and cover lightly with mix or vermiculite.
• Keep evenly moist but not waterlogged.

Provide the Right Conditions

• Light: Bright light after sowing.
• Temperature: 70°F (21°C) or warmer.

Germination

• Seedlings typically emerge in 7-14 days, though sprouting can be sporadic.
• Give strong light to prevent leggy seedlings.

Transplanting

• Pot up seedlings at the first true leaves; harden off before planting out.
• Plant out 3-4 weeks after the last frost; space 12 inches apart.

Care Tips

• Sun: Full sun.
• Water: Plant in rich, moist, well-drained soil; water deeply.
• Fertilizer: Balanced feeding; avoid excess nitrogen, which favors leaves over blooms.
• Pinch plants at 6-8 inches tall for bushier growth; stake tall types before they flop.

Bloom Time:

Summer to frost.
